' WHEEL Filed June 17; 1926 2 Sheets-Sheet 2 Patented Apr. 21, 1931 JOSEPH SCHULMAN, F BROOKLYN, NEW YORK WHEEL Application filed June 17,

This invention relates to vehicle wheels of the kind in which a portion carrying the tire is separable from a hub portion to facilitate the replacement, say, of a damaged tire.

More particularly the invention relates to securing means between the respective portions and has for its object the provision of easily operable securing devices which shall do away with the usual plurality of manually operable devices, such as nuts and bolts, customarily availed of to secure the parts together. According to the invention one of the wheel portions is formed with or carries elements adapted to automatically engage cooperating elements carried with the other portion upon relative movement between the wheel portions, certain of the elements requiring manual disengagement to permit the separation of the wheel portions. The invention may be applied between a disc wheel and the hub or between a demountable rim and the felly or its equivalent in a disc wheel. l/Vhen applied to a demountable rim the felly, say, is formed with or carries a plurality of hook means extending in a circumferential direction to receive eye-like instrumentalities carried with the rim upon relative movement therebetween, and a yielding catch means is also provided on the'felly to engage an abutment on the rim when the hook means and eye-like instrumentalities are in engagement to oppose their disengagement; the catch means requiring a positive manual operation to eflect its disengagement from'the abutment 3 when it is desired to remove the rim. The

invention also has for its object the adaptation of the conventional automobilewheels to the automatically engageable demountable rims made according to the present invention. This is accomplished by adapting hook means and catch means to besecured to the felly by the bolts which secure'the rims on the conventional wheels. Such adaptation can be 5 made by employing bolts in the same position on the felly. 7

These and other objects of the invention and the means for their attainment will be' more apparent from the following detailed description taken in connection with the ac- 1926. Serial No. 116,505.

Figures 7 and 8 are fragmentary sectional views similar to Figures 3 and 4: but showing a modification of the invention as applied to wheels of conventional construction.

Figure 9 is a fragmentary view in side elevation showing the modification of the invention illustrated in Figures 7 and 8.

Figure 10 is a sectional view taken in the plane indicated by the line 10-1O in Figure 2 looking in the direction of the arrows and showing the demountable rim with the protective annulus connected thereto and whereof one side is wedge-shaped to engage the wheel portion.

The invention has been illustrated as applied to a Wheel disc a mounted on a hub b supporting the axle c and turned at its periphery at right angles to form the rim receiving portion a which is again outwardly turned as at a to form a stop against which the rim d carrying the tire (not shown) abuts. The wheel disc at is formed on its side with a series of hooks e pressed outwardly from the metal and extending in a generally circumferential direction which are adapted to engage radially extending pins f carried by the rim d. To protect the securing devices and present a sightly appearance the pins f are disposed within an annulus f U-shaped in 7 are disposed circumferentially about the wheel and annulus, the hooks all facing in the same circumferential direction so that the rim may be mounted on the wheel by moving the same axially to position against the abutr nsment (1 and then rotating the parts relative to one another until the hooks engage the his to be noted that the hooks are so turned as'to receive the torque when the wheel is turning in .a forward direction, as illus- Y trated bythe arrow 00, for-instance.

tions to effect the engagement of the securing means.

The fastening devices are so arranged as to prevent unauthorized or accidental disengagement. To this end the action 'of a tool is required to cause the disengagement of the latch 9. Accordingly a lever-like tool it, conveniently provided with the handle h Y may be'used to push the latch outwardly, say,

by the shoulder 12?. on the pin 72: adapted to serve as a fulcrum when passing through the hole 9 in the latch and journaled in a hole Then upon rotating the lever about'the fulcrum in the direction of the arrow y the arm h fulcrumed within the wheel relative to one another until the hooks no longer engage the pins. The rimmay then be removed in anaxial direction.

In Figures 7 through 9 there is illustrat ed a modification whereby a wheel of conventional construction may be adapted to receive a demountable rim according to the present 7 The wheel A is provided with the usual bolts 2'. In this instance the hooks j are formed on a lug j having an axial hole y to receive the bolt 2' and be secured in -posi-' tion thereby to receive the pin fin the usual manner. Similarly the latch may be pivoted on an apertured lug 70' also secured to the wheel by a bolt iand pressed as before by the spring 9' into engagement with the stop f on the annulus f of the rim. The same tool It may be availed of with this modification also, a hole 7: being formed in the latch and a hole a in the wheel for the reception of the pin if. The rim is, of course, similar in every respect to that previously described.

If desired, the outwardly extending portion or shank of the hook e or j may be surrounded by yielding non-metallic material, such as a rubber washer Z which willbe compressedby the pin f and prevent rattle and wearbetween the parts and further by its resiliency or expansibility contribute to the ease of separation of the parts when they are turned relative to one another.

By the construction described, a vdemountable rim is provided which may be readily assembled and disassembled upon a wheel with a minimum of efiortand whereof the disassembly is prevented except upon a posltive manual operation.

Obviously the member f need notbe continuous but may comprise solely sup-porting and/or masking and protecting eye means on the rim.

Various modifications may be made in the disposition and configuration of the component elements going to make up the invention as a whole without departing from the spirit and scope of the invention.

What is claimed is: e

1. In a device of the character described, a wheel upon which a demountable tire rim is carried, a plurality of; hooks carried by the-side of the wheel and extending in the same circumferential direction thereabout, a demountable rim, a Ushaped annulus carried by the rim and facing the side of the wheel, and a plurality of radially extending pins secured between the arms ofthe U-shaped annulus to beengag-ed by the hooks, a spring pressedlatch carriedby the. wheel and'disposed to oppose the disengagement of the hooks from the pins, and an abutment carried with the annulus to be engaged by the latch.

2. In a device of the character described, a wheel upon which a demountable tire rim is carried, a plurality of hooks carried by the wheel and extending in the same circumferential direction thereabout, a demountable adjacent the abutment whereby a tool may enter therein for engagement with the latch and the annulus.

3. The combination with a Wheel, of a plurality of hooks carried by the side of the wheel and extending in the same circumferential direction thereabout, a spring pressed latch, having a hole through which a tool may enter, said latch being carried by the side of the wheel and facing in a circumferential direction to oppose the disengagement of the hooks, a demountable rim, a U-shaped annulus carried by the rim, facing the wheel and masking the hooks and latch, and a plurality of radially extending pins secured within the annulus to be engaged by the hooks, respectively, said annulus being formed with an aperture for engagement by the latch, and with a recess adjacent the hole in the latch for engagement by the tool. 20 This specification signed this 16th day of June, A.
